Description: 频域法加入数字水印的原理是首先将原始信号（语音一维信号、图像二维信号）变换到频域，常用的变换一般有DWT、DCT、DFT、WP和分形。然后，对加入了水印信息的信号进行频域反变换（IDWT、IDCT、DFT、WP），得到含有水印信息的信号。-Frequency-domain digital watermarking method by adding the principle is that first of all, the original signal (voice signal of one-dimensional, two-dimensional image signal) to frequency domain transformation, commonly used in general transform DWT, DCT, DFT, WP and fractal. Then, adding the watermark information signal to the frequency domain inverse transform (IDWT, IDCT, DFT, WP), received signal containing the watermark information.

Description: In this a DFT based Digital Image Watermarking Scheme is developed. Digital image watermarking is a technology for imperceptibly embedding various types of information into an image. The biggest challenge for image watermarking is manipulations and distortions of the images. These manipulations include changing the brightness/contrast levels, resizing, cropping, and noise addition. Here the work is to develop robust watermarking algorithms so as to recover the inserted watermark from the manipulated or attacked watermarked image.

Description: 本次研究主要内容是对音频信号进行数字水印加密技术的分析，数字水印技术作为保密技术的一种形式，将具有特殊含义的数据信息嵌入到数字媒体中，以达到对数字媒体进行辨识、标记和版权保护的目的。主要介绍几种水印的嵌入方法：相位法、回声法、时域方法、频域方法、小波域变换等。-Digital audio watermarking is nowadays gaining popularity among the original audio
content producers. It provides a way to the owner to prove ownership by using watermark
which forms integral part of audio. An approach is made in this paper to collectively
introduce applications and techniques up till developed for audio watermarking.The
proposedalgorithm is based on wavelet transform which has efficient computational load and also on cosine transform for increasing the watermark embedding capacity. Keywords: Watermark, audio, DFT, DCT, DWT, and DSSS.

Description: 本课题为基于MATLAB的小波变换dwt和离散余弦dct的多方法对比数字水印系统。带GUI交互界面。有一个主界面GUI，可以调用dwt方法的子界面和dct方法的子界面。流程包括，读取宿主图像和水印图像，嵌入，多种方法的攻击（剪切，加噪，旋转等），提取，最后利用psnr峰值信噪比进行评价不同攻击下，鲁棒性的好坏。(This project is based on MATLAB wavelet transform DWT and discrete cosine DCT multi method contrast digital watermarking system. With GUI interactive interface. There is a main interface GUI, which can call the sub interfaces of DWT method and DCT method. The process includes: reading host image and watermark image, embedding, attacks of various methods (cutting, adding noise, rotation, etc.), extracting. Finally, PSNR peak signal-to-noise ratio is used to evaluate the robustness of different attacks.)
